Abstract

A chemically self-copying paper intended for use in the com­ binations of a top sheet (CB), bottom sheet (CF) and one or more interleaving sheets (CFB) or a chemically copying, self-­ containing paper. The paper is formed of two fiber layers manufactured in separate wire sections and couched together while wet. The wire side of the upper fiber layer and the top surface of the lower fiber layer are couched together. The components inducing the color reaction are contained in the upper fiber layer which has been in contact with a smooth-­ surfaced press roll during the production of the paper.
